Abstract
A sliding bearing, which comprises a lining and a bismuth or bismuth-alloy overlay having improved compatibility and fatigue resistance is provided. The overlay is characterized by the following orientation. The relative ratio of the X-ray diffraction intensity I.sub.[hkl] of the bismuth or bismuth-alloy overlay defined below satisfies the following conditions (a) and (b): PA1 (a) the relative ratio of the X-ray diffraction intensity I.sub.[hkl] of planes other than the {012} planes is from 0.2 to 5 times as high as the ratio of the X-ray diffraction intensity I.sub.[012], namely, 0.2I.sub.[012].ltoreq.I.sub.[hkl].ltoreq.5I.sub.[012] PA1 (b) the relative ratio of the X-ray diffraction intensity I.sub.[hkl] of three or more planes other than {012} planes ranges from 0.5 to 2 times as high as the ratio of the X-ray diffraction intensity I.sub.[012], namely, 0.5I.sub.[012].ltoreq.2I.sub.[012].
